Its very easy that-6*5=30;
In exponent 10^(5+3)=10^8
So the ans is 30*10^8
In exponent 10^(5+3)=10^8
So the ans is 30*10^8

a^m*a^n = a^m+n.
6*5 = 30 normally multiple 10^5*10^3 = 10^8.
6*5 = 30 normally multiple 10^5*10^3 = 10^8.

= (6×1000)(5×10000),
= (6000)(50000),
= 300000000,
= 30×10'8.
= (6000)(50000),
= 300000000,
= 30×10'8.

= (6 x 10^3)(5 x 10^5).
= 6 x 5 x 10^(3 + 5),
= 30 x 10^8.
= 6 x 5 x 10^(3 + 5),
= 30 x 10^8.

(6x10^3)(5x10^5)
(6x5x10^3+5)
(30x10^8)
So ans is Option B
(6x5x10^3+5)
(30x10^8)
So ans is Option B

(6*10^3) (5*0^5).
6*5 = 30 and power 3+5 = 8.
30*10^8.
6*5 = 30 and power 3+5 = 8.
30*10^8.
